constexpr explicit flat_set(container_type cont, const key_compare& comp = key_compare());
Effects: Initializes c with std::move(cont) andcompare with comp, sorts the range [begin(), end()) with respect to compare, and finally erases all but the first element from each group of consecutive equivalent elements.
Complexity: Linear in N if cont is already sorted with respect to compare and otherwise NlogN, where N is the value of cont.size() before this call.
